I actually only need the two ends in the back seat. Not the clip with release button but the other end. Where can I get these?

If you're looking for real nice repros, ...there is a place, ...snake-oyl products (I believe in Texas).
I had purchase a complete set for my '67 from them, ...they were not cheap, ...but awsome quality.
...for some reason I can't get to their website, ...I thought it was http://www.snakeoylproducts.com , ...but this I believe is their # 1-800-284-7777

...now for some reason the site works, ...but it appears to go to a VIper site, ....??????? ...it may be worth a call...

www.ssnake-oyl.com is the correrct site... I got mine made there with date code correct labels........Also had my shoulder belts redone there....A bit procey but excellent work and quality.........D

I dont want to spend a fortune there for the rear seats. NPD has a couple sets Im looking at.

Watch ebay. If you don't need correct dates, you can find bits and pieces fairly cheap. Also KevinW may have some extras. If you need labels, he may be able to help.
